Living with Dystonia 24

A rare inherited dystonia that affects the neck, eyelids, jaw, and voice, usually starting from childhood to adulthood.

Understanding Dystonia 24

Dystonia 24 is a rare inherited form of dystonia that affects the head, neck, voice box, and sometimes the arms.

It causes a mix of neck dystonia with tremor, eyelid spasms (blepharospasm), and dystonia in the jaw and voice box. It slowly gets worse and may spread to other areas. Arm tremor and brief muscle jerks (myoclonus) in the arms or neck have also been reported. Symptoms begin between childhood and adulthood.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Wry neck (torticollis)
  • Eyelid spasms (blepharospasm)
  • Muscle tightening in the limbs (limb dystonia)
  • Shaky voice (vocal tremor)
  • Jaw dystonia (less common)
  • Muscle jerks (myoclonus; less common)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists and genetic specialists.

  3. Consider genetic testing

    Changes in ANO3 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    Dystonia Medical Research Foundation may keep lists of experts for this condition.
